| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier in its category. The first AI music tool I'd actually listen to. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. |
